Microsoft Work IQ: the agent stops indexing Microsoft 365

RAG over Microsoft 365 used to be your pipeline: a connector, a vector index, a sync job and permissions re-created by hand. Microsoft Work IQ takes that pipeline out of your hands — and charges in identity: there is no application-only authentication, every call runs as a person and tenant policy blocks writes by default. This article shows what changes, what stays with you and how to compose Work IQ with Foundry, Microsoft Fabric data agents and Databricks Genie without swapping the identity on the way.

Fabric IQ: the ontology is now a workspace item and refresh has a price

The demo convinces, the workspace disagrees. In Microsoft Fabric the ontology is now a real item: a REST API, a definition in files and a child graph created on its own — and it is that child that issues the bill. This article gathers what the item really is, why every refresh is full and freshness became a cost decision, the four capacity meters, how far binding actually reaches, three points where the official documentation contradicts itself — and what has to be in place before switching this on in production.

Azure AI Content Safety: how to stop indirect prompt injection

The user prompt was clean. The hostile instruction came in through the content the tool brought back — and that is the door almost no security review looks at. This article gathers what moved in the 2026 OWASP Top 10, the two Prompt Shields intervention points, the spotlighting that ships off by default, what the MCP specification protects and what it leaves to you — and shows what has to be in place so a successful injection does not become impact.

Fabric data agent: five sources, 25 rows and English only

Five sources per agent, answers capped at 25 rows by 25 columns, documented support for English only, and read-only queries: the Fabric data agent has an entry contract no prompt renegotiates. This article gathers the six source categories, the output limits, the asking user’s identity, and the two retirements of 26 August — and shows what has to be in place before the pilot becomes a commitment to the business.

A reranker cannot fix what search never retrieved: retrieval quality in RAG

When a RAG agent answers wrong, the model is rarely at fault: the right passage never reached the context. This article splits retrieval into three budgets that fail for different reasons — recall, precision, and passage context — and shows what fixes each one: structure-aware chunking, hybrid search with rank fusion, second-stage reranking, and retrieval measured separately from the answer.

Entra ID in Foundry: agent identity is provisioned, accountability is not

Microsoft Entra Agent ID reached general availability, and in Microsoft Foundry the agent identity is provisioned for you. Understand blueprints, the shared project identity and the RBAC that does not carry over on publish, why a sponsor is required at creation, how leaver workflows transfer sponsorship to prevent orphaned agents, and why the token subject decides where a Conditional Access policy actually lands.
